" According to scientists, there are three stages of love: lust, attraction, and attachment. And, it turns out, each of the stages is orchestrated by chemicals—neurotransmitters—in the brain.
As you might expect, lust is ruled by testosterone and estrogen.
The second stage, attraction, is governed by dopamine and serotonin. When, for example, couples report feeling indescribably happy in each other’s presence, that’s dopamine, the pleasure hormone, doing its work.
Taking cocaine fosters the same level of euphoria. In fact, scientists who study both the brains of new lovers and cocaine addicts are hard-pressed to tell the difference.
The second chemical of the attraction phase is serotonin. When couples confess that they can’t stop thinking about each other, it’s because their serotonin level has dropped. People in love have the same low serotonin levels as people with OCD. The reason they can’t stop thinking about each other is that they are literally obsessed.
Oxytocin and vasopressin control the third stage: attachment or long-term bonding. Oxytocin is released during orgasm and makes you feel closer to the person you’ve had sex with. It’s also released during childbirth and helps bond mother to child. Vasopressin is released postcoitally.
Natasha knows these facts cold. Knowing them helped her get over Rob’s betrayal. So she knows: love is just chemicals and coincidence.
So why does Daniel feel like something more? "

" All that happens in the human brain is but the result of electro-chemical reactions. Be it of love, hate, of pleasure, of suffering, of imagination, or all other states of mind, sentiment or sickness; the process depends in every case on the chemical reactions produced in the interior of the brain, and the resulting electrical impulses or messages, be they visual, auditory, based on memory, or an interpretation of new events based on elements that one has in the memory.

" Watching her, I remembered a girl I'd known in school, a grind, Mildred Grossman. Mildred: with her moist hair and greasy spectacles, her strained fingers that dissected frogs and carried coffee to picket lines, her flat eyes that only turned toward the stars to estimate their chemical tonnage. Earth and air could not be more opposite than Mildred and Holly, yet in my head they acquired a Siamese twinship, and the thread of thought that had sewn them together ran like this: the average personality reshapes frequently, every few years even our bodies undergo a complete overhaul--desirable or not, it is a natural thing that we should change. All right, here were two people who never would. That is what Mildred Grossman had in common with Holly Golightly. They would never change because they'd been given their character too soon; which, like sudden riches, leads to a lack of proportion: the one had splurged herself into a top-heavy realist, the other a lopsided romantic. I imagined them in a restaurant of the future, Mildred still studying the menu for its nutritional values, Holly still gluttonous for everything on it. It would never be different. They would walk through life and out of it with the same determined step that took small notice of those cliffs at the left. "

" Just the other day, I was in my neighborhood Starbucks, waiting for the post office to open. I was enjoying a chocolatey cafe mocha when it occurred to me that to drink a mocha is to gulp down the entire history of the New World. From the Spanish exportation of Aztec cacao, and the Dutch invention of the chemical process for making cocoa, on down to the capitalist empire of Hershey, PA, and the lifestyle marketing of Seattle's Starbucks, the modern mocha is a bittersweet concoction of imperialism, genocide, invention, and consumerism served with whipped cream on top.

" The conundrum of the twenty-first (century) is that with the best intentions of color blindness, and laws passed in this spirit, we still carry instincts and reactions inherited from our environments and embedded in our being below the level of conscious decision. There is a color line in our heads, and while we could see its effects we couldn’t name it until now. But john powell is also steeped in a new science of “implicit bias,” which gives us a way, finally, even to address this head on. It reveals a challenge that is human in nature, though it can be supported and hastened by policies to create new experiences, which over time create new instincts and lay chemical and physical pathways. This is a helpfully unromantic way to think about what we mean when we aspire, longingly, to a lasting change of heart. And john powell and others are bringing training methodologies based on the new science to city governments and police forces and schools. What we’re finding now in the last 30 years is that much of the work, in terms of our cognitive and emotional response to the world, happens at the unconscious level. "
